'Ihis invention relates to lidded boxes or receptacles and more particularly to those having hinged lids, and while the invention will be described with particular reference to boxes for containing the inking pads for india-rubber stamps, it will be obvious that it may be applied to boxes or receptacles for many other purposes; for example, desk and like cigarette boxes.

The object of the invention is to provide a box,

the lid or cover of which may be opened by a slight tap or pressure of the iinger on the lid or cover itself without the necessity of applying or using any means for holding the body of the box ,while the lid is being raised, and to this end according to this invention the front wall of the box is furnished with a centrally disposed projection and the front Wall of the lid or cover'is furnished with a centrally disposed aperture or catch adapted to engage with said projection;

g@ the front wall of the box is further provided with means for limiting the extent of closure and on which the iront part of the lid is adapted to have a slight rocking movement when de.

pressed at one of its front corners or extreme ends, which rocking movement serves to effect the disengagement of the catch so that the lid is free to open automatically under the action of a suitably disposed spring.

In the accompanying drawing which` illusau trates this inventionr- Figure 1 is a front elevation of a box containing an inking pad in the closed position;

Figure 2 is a similar view to Figure 1 showing the method of opening the box; I

Figure 3 is a plan of the box in the open position with part of the lid broken away;

Figure 4 is a vertical section on the line IV--IV of Figure 1, and,

Figure 5 is a front elevation partly in section lo of a modication.

The side walls I and the front wall 2 of the box are al1 of the same height and are provided on their upper edges with inwardly directed flanges 3 and 4 which retain the inking pad 5 in position within the box. The front wall 2 a short distance from its upper edge is furnished with a centrally disposed projection 6 and two further projections or stops 'I, hereafter referred to as the releasing stops, are furnished one on each side of and somewhat below the level of the centrally disposed projection 6. The lid or cover 8 is attached by means of a hinge pin 8 to the rear wall I Il of the box, said hinge pin 9 being furnishedwith springs II which tend to retain the lid 8 in its fully open position.

(Cl. 22o-35) The lid 8 is furnished with side walls I2 and a' front wall I3 which, when the lid 8 is closed, overlap the side and front Walls I and 2 of the box and the front wall I3 of the lid 8 is furnished with a centrally disposed aperture or catch I4 with which the projection 6 on the box is adapted to engage. In use, the lid 8 is maintained in the closed position by the projection 6 on the box entering and engaging the aperture I4 infthe front wall I3 of the lid 8. When it is desired to open the box, pressure is applied to the top of the lid 8 adjacent one end or front corner, as shown in Figure 2, thus bringing the lower edge of the front wall I3 into contact with the releasing stop 'I adjacent that end; this action causes the lid 8 to rock and effects the disengagement o f the projection 6 from the aperture It, and when the hand is removed from the lid 8 it automatically springs into the open position under the action of the spring 9.

According to a modified form of the invention illustrated in Figure 5, the releasing stop or stops Il are replaced by an upwardly disposed ex-l tension I5 of the front wall 2 oi? the box (hereafter referred to as the releasing extension) the top edge I8 of said releasing extension being cambered so that the depth is less'at the ends than at the centre.

In use, the lid or cover is maintained in the closed position by the projection on the box as in the embodiment rst described, and when it is desired to open the box a tap or light pressure on one of the front corners oi the lid causes said lid to rock on the cambered edge i6 of the releasing extension It and thereby effects the disengagement of the projection from the lid.

The position of the releasing stop or stops 'i and the height of the curved releasing extension l5 when applied to boxes for containing inking pads, is such that when depressed to the maximum extent the inner face of the lid or cover will not make contact with the face of the inking pad.

In order to prevent the lid or cover flying back at against the desk or other supporting surface, the upper edge of the rear wall I0 where it is usually cut away to form the hinge, is bent round E the box, a centrally disposed catch on the front wall of the lid adapted to coact with said projection to maintain said lid in the closed position and means on the front wall oi' the box for limiting the extent of closure and on which the iront part of the lid has a slight rocking movement when depressed at one of its front corners, which rocking movement serves to etiect the disengagement o! the catch so that the lid is free to open automatically under the action oi' the spring.

2. A lidded box comprising a box-portion and a lid. a hinge connecting said box and lid together along the back edge, springs on said hinge tending to maintain the lid in the open position, a centrally disposed projection on the front wall of the box, a centrally disposed catch on the front wall of the lid adapted, to coact with said projection to maintain said lid in the closed position and means comprising a further projection on the front wall of the box on either side of the central projection for limiting the extent of closure and on which the front part of the lid has a slight rocking movement when depressed at one of its front corners, which rocking movement serves to effect the disengagement of the catch so that the lid is free to open automatically under the action of the spring.

3. A lidded box comprising a box-portion and a lid, a hinge connecting said box and lid together along the back edge, springs on said hinge tending to maintain the lid in the open position, a centrally disposed projection on the front wall of the box, a centrally disposed catch on the front wall of the lid adapted to coact with said projection to maintain said lid in the closed position and means comprising an upwardly disposed extension on the front wall oi the box, the top edge of said extension being cambered so that the depth is less at the ends than at the centre for limiting the extent of closure and on which the front part of the lid has a slight rocking movement when depressed at one of its front comers, which rocking movement serves to effect the disengagement of the catch'so that the lid is free to open automatically under the action of the spring.

4. A lidded box comprising a box portion and a lid, a hinge connecting said box and lid together along the back edge, springs on said hinge tending to maintain the lid in the open position, a centrally disposed projection on the front wall of the box, a centrally disposed catch on the front wall of the lid adapted to coact with said projection to maintain said lid in the closed position, means on the front wall of the box for limiting the extent or closure and on which the iront part of the lid has a slight lrocking movement when depressed at one of its front corners, which rocking movement serves to effect the disengagement of the catch so that the lid is free to open automatically under the action of the spring, and means for limiting the extent of opening of the lid.
